How is misinformation about the war in Ukraine...

Oxford Sparks Big Questions ·

2022/04/20

Misinformation about the war in Ukraine - and countless other topics, such as the pandemic and climate change - spreads like wildfire online. It aims to confuse people, make them question their own knowledge, and ultimately raise suspicion and doubt. But how exactly does this misinformation spread, why is it so prevalent on social media, and what are the various platforms doing to help prevent it? We chat to Dr Aliaksandr Herasimenka from the Oxford Internet Institute to find out.

How does a pandemic end?

Oxford Sparks Big Questions ·

2022/04/06

Masks, social distancing, lockdowns. We've become intimately familiar with numerous COVID-19 control measures over the past two years. Now, with most restrictions gone (at least here in England), does that mean that the pandemic is really over? In this episode, we chat to Erica Charters, Professor of the Global History of Medicine at the University of Oxford and Principal Investigator of the 'How Epidemics End' interdisciplinary project.

Why do we develop bad habits?

Oxford Sparks Big Questions ·

2022/03/23

From biting our nails to idly scrolling on our phones, we all have those habits we wish we didn't. In this episode of the Big Questions Podcast, we chat to neuroscientist Charlotte Collingwood about what makes a habit, why we develop them, and how we might go about kicking a bad habit.

Is the energy crisis going to get worse?

Oxford Sparks Big Questions ·

2022/03/09

Over the past year, we've seen our energy bills reach unimaginable heights. The war in Ukraine is having devastating effects for Ukrainians and creating ripples for international fuel costs. We're now in the midst of a 'perfect storm' when it comes to energy supply - but where are we in the story? Is the energy crisis going to get worse, and what are the potential solutions to bringing those prices down? We chat to Phil Grünewald who considers the current situation a wake-up call to improve our

Is ordering a pizza bad for the climate?

Oxford Sparks Big Questions ·

2022/02/23

In this episode of the Big Questions podcast, we're talking about one of our favourite guilty pleasures - ordering a pizza! From the machinery required to harvest the wheat for the dough, to the cardboard packaging your finished pizza is delivered in, we're considering all aspects of a pizza's journey and asking: is ordering a pizza bad for the climate? Environmental scientists Eleanor Hammond and Dr Mike Clark are here to provide some answers, and tell us about '4 steps 4 the Earth'. (Don't worry,

How do you monitor mosquitoes using their sound?

Oxford Sparks Big Questions ·

2022/02/09

What do you think of when someone says “the most dangerous animal in the world”? A lion perhaps? Or a poisonous frog? Well, one species of mosquito – Anopheles gambiae – is often referred to as such, owing to its enhanced ability to transmit malaria, a deadly disease which led to 627,000 deaths in 2020 alone. A. gambiae isn’t the only species of mosquito that is able to effectively transmit malaria, and each species exhibits different behaviours and requires a different management strategy. But how

How can we improve endometriosis treatment?

2022/01/26

Did you know there are different types of pain? In this episode of the Big Questions Podcast, we chat to Dr Lydia Coxon, a researcher in the Nuffield Department of Women's and Reproductive Health at Oxford. Lydia is looking at the mechanisms that cause pain in patients with endometriosis - a common gynaecological condition where tissue that normally grows inside the womb is found outside the womb. Through her research she hopes to better understand the type of pain that endometriosis causes, so that

Why build a magnetically shielded room?

Oxford Sparks Big Questions ·

2022/01/12

One way to delve deep into the ancient history of the Earth - or other planetary bodies for that matter - is to examine the magnetism recorded by rocks. Kind of like a fossilised magnetic fingerprint. But trying to do this in an environment where another magnetic field exists (i.e. everywhere on Earth!) is pretty challenging. Enter the 'magnetically shielded room'! Join us as we catch up with Prof James Bryson from Oxford's Department of Earth Sciences, and find out all about this very special DIY

Why is Rudolph's nose red?

Oxford Sparks Big Questions ·

2021/12/22

"Rudolph the red-nosed reindeer, had a very shiny nose..." Many of us will be very familiar with Santa's famous antlered friend. But did you know that many reindeer actually do have red noses? But why? In this festive episode of the Big Questions Podcast, we ask Oxford polar biologist Ignacio (Nacho) Juarez Martinez to share some of the reasons we find red pigments in animals, and to explain why he thinks Rudolph's nose is so red!

How do you tackle hate speech one emoji at a time?

Oxford Sparks Big Questions ·

2021/12/08

Online communication channels are popular, to say the least. For instance, there are 187 million active Twitter users per day alone. Sadly, these open channels of communication also open up the potential for harm, through online hate speech. The problem is so large that we require AI to help detect it. But what about when it comes to emoji? According to some reports, ten billion emoji are sent in messages around the world every day. When the same emoji can have vastly different meanings depending on

Umm...Should I be wearing a mask?

Oxford Sparks Big Questions ·

2021/11/24

In the early days of the COVID-19 pandemic there was a lot of confusion, as we all tried to figure out what we should and shouldn't do to best protect ourselves and others. Fortunately, we now have more definitive answers to some of our most pressing questions - which are backed-up by data - including "umm...should I be wearing a mask?". As COVID cases are again on the rise across Europe, this is the question we're putting to demographer and behavioural scientist Prof Melinda Mills.

How can satellites prevent mining disasters?

Oxford Sparks Big Questions ·

2021/11/12

Satellites have been orbiting our planet for the past few decades. We might be familiar with how they can be used to track weather, or beam television and phone signals around the world. But did you know, that by capturing images of the Earth outside the visible spectrum, they're able to offer a unique perspective of the ground beneath our feet? They could even - as Earth observations specialist Maral Bayaraa tells us - provide a remote early warning system for an environmental catastrophe, dam

How do you stop megafires?

Oxford Sparks Big Questions ·

2021/11/03

From California to Greece to Australia, it seems like every time we switch on the news there's another wildfire report. Some fires are natural - in fact, they're a fundamental part of many ecosystems - but the severity and frequency of the wildfires we are now witnessing is beyond natural levels. Human-ignited "megafires" are causing devastation across the planet. Climate change and inadequate ecosystem management are key contributors to the problem, but what are the possible solutions?

Could chocolate go extinct?

Oxford Sparks Big Questions ·

2021/10/20

Chocolate. It’s rare to find anyone who isn’t partial to a square or two of this delicious treat. But is its very existence in danger? (*Cue worried faces.*) In this episode of the Big Questions Podcast we chat to chocoholic and researcher Acheampong Atta-Boateng, who studies the relationship between cocoa trees and their micro-pollinators. We hear about how monocropping, pesticides and climate change all pose a risk to the cocoa tree and ask – could chocolate go extinct?

Should all robots have an ethical black box?

Oxford Sparks Big Questions ·

2021/06/23

Nowadays, the idea of encountering robots in our daily lives isn't pure science fiction. Many of us interact with AI every day, and the use of robots in, for example, healthcare settings, is already on the horizon. But what if something goes wrong? The RoboTIPS team at the University of Oxford is developing an innovative feature - an 'ethical black box' that acts like a data recorder for use when adverse incidents or accidents occur. How would it work? Well, in this very special episode of the Big

Is a snack tax on the horizon?

Oxford Sparks Big Questions ·

2021/06/09

Do you remember when the price of fizzy drinks in the UK went up slightly a few years ago? Soda fans, perhaps you remember all too clearly...! Well, this was because the UK government introduced a sugar tax (or the Soft Drinks Industrial Levy, to be precise), requiring manufacturers to pay a tax on sugary drinks - a cost which was then passed on to the customer. Following the success of this tax (perhaps not for your pocket, but fizzy drinks now contain less sugar) we're asking public health

What's an arboretum anyway?

Oxford Sparks Big Questions ·

2021/05/26

An arboretum could be described as a "living library". A beautifully curated collection of woody plants from across the globe, each one carefully labelled and managed. In this episode of the Big Questions Podcast we chat to Ben Jones, Arboretum Curator at the University of Oxford Botanic Garden and Harcourt Arboretum, about what makes an arboretum so special.

Did the pandemic make us moodier?

Oxford Sparks Big Questions ·

2021/05/12

Lockdowns, social distancing, restrictions on 'normal' activities - we've all been affected by the COVID-19 pandemic. But how has it impacted on our mood and mental wellbeing? We chat to Dr Maxime Taquet from the Department of Psychiatry about 'mood homeostasis' (the interplay between people's activities and the way they feel), and how this has been affected over the past year. He also tells us about a new study into the impact of COVID-19 infection itself on mental health.

Will climate change kill off the great tits?

Oxford Sparks Big Questions ·

2021/04/28

Their distinctive 'teacher teacher' call is synonymous with British gardens, but great tits are facing a big problem - climate change. As our springtime becomes warmer and begins earlier, peak caterpillar abundance is also shifting earlier. As a crucial food source for great tit chicks, this is cause for concern. In this episode of the Big Questions Podcast, we catch up with ecologist Dr Charlotte Regan, one of the scientists who monitors the Wytham Woods great tit population, which has been

Can we build an eco-friendly aeroplane?

Oxford Sparks Big Questions ·

2021/04/14

Remember those days when it was possible to climb aboard a plane and jet off around the world? Well, while we might be yearning for foreign shores, there's no denying that air travel comes with a big ol' carbon footprint. But is it possible to make aeroplanes 'greener'? We chat to Dr Chiara Falsetti, a researcher at the Oxford Thermofluids Institute, who is looking at ways to improve the cooling mechanisms of aircraft engines, to boost their efficiency and ultimately make flying more
